The same cap D versus cap V plot for a jet is shown as before, but now with three tangent lines. The original line intersecting the drag curve at cap V sub cap M cap R is present. A second line for a tail wind is shown, which begins at a negative cap V value corresponding to cap V sub w tail, causing it to intersect the drag curve at a lower cap V value, labelled cap V sub cap M cap R tailwind. A third line for a head wind is shown, which begins at a positive cap V value corresponding to cap V sub w head, causing it to intersect the drag curve at a higher cap V value, labelled cap V sub cap M cap R headwind.
